At higher redshift the only possibility of observing the 400 nm and 520 nm bands is using future space-based telescopes. This figure illustrates the predicted AB magnitude for SLSN Ic out to z 10. The solid line is the peak magnitude of M(400) = −21.86 derived here. The lower dotted line is a 1σ scatter on the peak magnitudes, and the upper dotted line illustrates the depth required to reach +20 days after peak to apply the ΔM₂₀(400) correction discussed here (addition of the typical 13 decline). No foreground extinction has been applied to the estimated magnitudes because the Milky Way foreground will be minimal at these wavelengths.
